ALBERT RUSH, on commnus, OHIO, ASSIGNOR '10 THEKINNEAR mannrnc'rumnaCOMPANY, or comnunns, omo, A conroan rron or care DOOR FOB HANGABS ANDOTHER STEUC'IUBES Application filed. November 12, 1927. Serial No.232,775.

Owing to the horizontal spread of the planes or wings of a flyingmachine or the enormous-size of a dirigible-balloon a hangar or otherhousing for such a device must have a'veny wide entrance, and because ofsuch width it does not appear to be economically practical to providesuch an entrance with a single rolling steel door.

- door should have vertical guiding and retaining channels for itsedges, hence if a plurality of doors is to be provided for the entranceof a hangar there is presented the problem of displacing such guidingchannels or posts containing one or more of them when the entrance is tobe opened. The present invention, therefore, has for its principalobject the solution of such problem. The invention also has for itsobject the solution of such other problems as will hereinafter appearand as may be collateral to the principal problem.

The invention is embodied in the examples herein -shown and described,the features of novelty being finally claimed.

In the accompanying "drawing- Figure 1 is a view in elevation of theentrance end of a hangar equipped with the invention.

Fig. 2 is a combined vertical section and elevation, broken outhorizontally and looking toward the channel-side of one of the posts.

Fig. 3 is front view looking to the left, at the parts of Fig. 2, theclutch for operating the door being disengaged.

Fig. 4 is a somewhat similar view with the trolley frame broken out tobetter illustrate details. h

Fig. 5 is an edge view on a larger scale and with a part in sectionlooking toward the channel side of a post showing hand-worked means foroperating the door.

Fig. 6 is a detail section on line VI of Fig. 5 showing means for movingone of the clutch members shown in of engagement with the other clutchmember.

Fig. 7 is a front View of the post shown in Fig. 5 with the clutchmembers engaged and the operating crank removed.

Fig. 8 is a view like that shown in Fig. 2 with electrically operatedmeans for working 50 the door.

A steel rolling the hoods of the rolling Fig. 5 into andout- Fig. 9 is afront view of the post as constructed in Fig. 8.

Fig. 10 is a detail edge view of the post showing the circuit extendingmeans removed.

Fig. 11 is a similar view showing the circuit extending means applied.

Fig. 12 is an end elevation of the circuit extending means looking tothe right as seen in Fig. 11.

In the views the character 15 designates the building with the entrancethereto at 16. In-

stalled upon the front wall above the entrance -is a plurality offlexible steel rolling doors 70 covered with hoods 17, 17 and 17 therolling doors being of the usual construction with winding shafts 12 andend brackets 13. These rolling doors are preferably counterbalanced, asusual in that type, so that each of them can be easily unrolled androlled up and remain in rolled up condition when the means forperforming these operations is removed. 1

Mounted on the wall of the building above doors are suitable, brackets18 to the lower faces of whichare secured strips 19 provided withtrolley tracks 20, 20, extending parallel to the tops of the hoods. 21designates a stout frame of-reversed. c-form, roughly, as viewed in Fig.2, to the lower arm of which is secured a post 23 having curtain guidingand retaining channels 24 at its opposite vertical sides to receive andguide the adjacent edges and margins of two of the doors or curtains.Only the intermediate posts require two door guiding channels andonlyone of the end or stationary corner posts requires curtain operatingmeans. The upper arm of the frame 21 is equipped with suitable trolleys25 that en age the tracks 20, 20, said tracks and tro leys supportingthe frame 21, the post 23 and the parts attached thereto, and permittingthe horizontalmovement of said parts across the entrance of thebuilding.

Referring now more par icularly to Figs. 2-7, inclusive, the roller orwinding arbor of the flexible door has at one end a large spur gear 26permanently engaged by a spur gear pinion 27, the shaft of which isprovided with a bevel pinion 28 engaged by a bevel pinion 29 on theupper end of a shaft supported in a bracket 30 on the main end bracketof the rollin door, the lower end of ls)aid last named sha having aclutch mem- On the face of the post is journaled vertically a shaftcomposed'of two parts 32 and 33. Pinned to the upper end of the uppershaft part 32 is a clutch member 34 while the lower 'end enters an axialopening in an externally threaded member 35 that is pinned to the upperend of the shaft part 33. The said threaded member 35 is slitlongitudinall at 35*: between its ends, the shaft part 32 t erein beingprovided with a cross pin 32 entering the slits 35 to cause the clutch34 to turn when the threaded member 35 is turned by the shaftpart 33. Onthe lower end of the shaft 32 is a sleeve 36 threaded internally toengage the .threads of the member 35, said sleeve 36 having at its upperend a hand wheel whereby it may beturned. The shaft part 32 is providedwith a thrust collar 14 pinned toit,'hen'ce when the sleeve 36 is turnedin one direction the clutch member 34 is raised to engage the clutchmember 31; and when turned in the opposite direction permits the clutchmember 34 to drop away from the clutch member 31. The cross pin 32 makesa sliding coupling betwen the shaft parts 32 and 33 while the threadedmembers permit extension and contraction of the clutch working shaftparts. The shaft 32 has pinned to its lower end a bevel ear 37 engagedby a bevel gear 38 having a s aft 39 provided with a s uared end 39 toreceive a removable cran arm 40 for turning in the desired direction thetwo parts together with the clutch members when coupled and the largegear of i the door winding shaft to wind up or unwind and lower theflexible door. The bracket or housing 44 in which the bevel gears 37 and38 are contained can be provided with a beep 42 hinged thereto,said-hasp provided with a .cover .42 to fit over the squaredcrank-receiwing-end of the shaft when the hasp is turned up to position for thepurpose and looked upon a sta le 43 to prevent unauthorized operation 0the doors. The posts are provided at their .lower ends with suitableslidbolts 45 to engage sockets in the floor or in sill to preventswaying of the doors and posts when subjected-to heavy wind pressure.

' 'In' Fig. 1 one ofthe 'doors-isshown as eclosed, with one of theintermediate posts in it is only necessary position to permit operationof the rolling oor. "To operate such door to raise the same lowered byturning the crank 40 in the oppov to turn the crank 40in the properdirectlon toturn the, clutches 31-34 and the bevel pinion 29. The dooris .53 supported on a suitable bracket 54 secured to the inner side ofthe wall. The electric circuit for the motor 53 includes wires 55 thatterminate in suitable spring contacts 56 in a suitable frame 57 securedto the lintel of the doorway. The circuit connecting device is carriedon the inner end of a lever 58 that extends through the post 23 and isfulcrumed on a bracket 59. The circuit connecting device has a plate 60for carrying contacts to close with the contacts 56, and its positionfor connecting and extending-the circuits is controlled manually by achain 61 that passes through a flexing member 62 and a chain detainingdevice at 63 to hold the circuit closer u p in circuit extendingpositionwhen the electric motor is to be operated. When the post is tobe moved horizontally after the curtain has drawing down the chain 61and latching it as before described. The Wires from the plate 60 areextended through a tube, 64 on the front of the post to a. boxcontaining three spring push buttons 65, 65 and 65 for the purpose ofoperating the motor in direct or reverse to raise or lower the curtainand to stop the motor and curtain at any point desired. The plate '60 isprovided with a wedge-shaped guiding portion 66 that enters a socket inthe base of the structure carrying the contacts 56.

While I have'shown and described the inventionas applied to buildingsfor-receiving aerial vehicles" it will be understood that the inventioncan be used in connection with any 7 structure where it is desirable toclose a wide opcning'or to remove a channel carrying post.
